The etch provides semiconductor fin portions that have exposed vertical sidewalls. A doped semiconductor material is then formed from each exposed vertical sidewall of each semiconductor fin portion, followed by an anneal which causes diffusion of dopants from the doped semiconductor material into each semiconductor fin portion and the formation of source/drain regions. The source/drain regions are present along the sidewalls of each semiconductor fin portion and are located beneath the dielectric spacers.
